However, I always keep Firefox installed and updated as well - and will often use it interchangeably (although Chrome serves as my default browser, both browsers are side-by-side on my windows quicklaunch bar). Edit: To clarify, IE doesn't even earn a place on the launch bar any longer - I've even removed it from my start menu at home to prevent accidental usage.

Firefox still serves as a backup browser for some websites that Chrome doesn't handle properly for some reason.

Strangely enough - I even used Chrome during the "dark days" before it had an ad blocking extension. And suffered a degraded browsing experience compared to firefox because the speed and pleasure of using Chrome outweighed the desire to block ads. I guess everyone has different priorities.
